While remote debugging I copied a long value from the watch area.
Pasting it resulted in a partial string with '...' at the end

To Reproduce

1. Start a debugging session
2. add an expression that has a long value to watch
   
3. Copy value
4. paste it somewhere in a text area
5. the pasted text appears is limited and ends with '...'
   

Additional context
Initially I've opened a ticket here microsoft/vscode#97444
I was told to open it here and mention:

VSCode sents the clipboard context when copying. Their extension should set the capability supportsClipboardContext and respect the clipboard context by evaluation the full thing.

You can work around this by adding the following to your launch.json with setupCommands or running it in the debug console with -exec:
set print elements 0.

The correct fix is to run set print elements 0 before evaluating the request when it is a clipboard context and then reset it back to the value of show print elements before we changed it to 0.

HI,

I'm facing this very same issue while debugging Rust, as described here into details: rust-lang/rust-analyzer#15619.

VsCode: 1.82.2
CppTools extension: v1.17.5

My launch settings are:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(Windows) Launch",
            "type": "cppvsdbg",
            "request": "launch",
            "preLaunchTask": "rust: cargo build",
            "program": "${workspaceFolder}/target/debug/${workspaceFolderBasename}.exe",
            "args": [],
            "stopAtEntry": false,
            "cwd": "${workspaceRoot}",
            "environment": [],
        }
    ]
}

Any suggestion?
